Paper Abstract

We present a special facility for accurate calibration of instrument’s irradiance responsivity in ultraviolet spectral region to overcome the troubles caused by the weak ultraviolet response of most spectral radiometer and poor signal-to-noise ratio. In this system, a Seya-Namioka monochromator with a small f-number is designed to get more energy as an irradiance source. Reference standard irradiance detectors, calibrated against to primary standard detector traceable to cryogenic radiometer for spectral power responsivity, are used to determine the irradiance at a reference plane. The typical combined standard uncertainties in irradiance responsivity calibrations using this system can be 2.3%.
